...To synthesize a polymer compound, it is common to combine a large number of low molecular weight raw materials (monomers) that correspond to the building blocks to form a large molecule, and this type of reaction is called a polymerization reaction. In this polymerization reaction, polymerizing two or more types of monomers at the same time is called copolymerization, and the product is called a copolymer. Polymers produced by copolymerization contain structural units derived from the raw monomers. Therefore, the properties of a copolymer are different from polymers made from each single monomer (homopolymers) and from mixtures of these. ... From [Polymer] ...Polymers are produced by polyaddition, ring-opening polymerization, and addition-condensation polymerization, in addition to condensation polymerization and addition-condensation polymerization. [Polymer]...The formation of polyester, as mentioned above, is an example of this (condensation polymerization reaction). A polymer that has structural units based on two or more types of monomers, such as ethylene and propylene, in its molecule is called a copolymer. In contrast, a polymer that consists of structural units of only one type of monomer is called a homopolymer. *Some of the terminology that mentions "copolymer" is listed below.

…高分子化合物を合成するには,その構成単位に相当する低分子化合物の原料(単量体,モノマー)を多数結合させて巨大な分子とするのが一般で,このような反応を重合反応という。この重合反応において,2種類以上のモノマーを同時に重合させることを共重合といい,その生成物を共重合体(コポリマーcopolymer)という。共重合によって生成する高分子の中には,原料のモノマーに由来する構造単位が存在する。したがって共重合体の性質は,それぞれの単一モノマーだけからの高分子(単独重合体,ホモポリマーhomopolymer)とも,またそれらの混合物とも異なっている。… 【高分子】より…縮合重合と付加重合のほか,重付加,開環重合および付加縮合によっても高分子が生成する。重合 【ポリマー】より…上に例をあげたポリエステルの生成はこれに当たる(縮合重合反応)。エチレンとプロピレンのように2種類あるいはそれ以上のモノマーにもとづく構造単位を分子の中にもつポリマーをコポリマーcopolymer(共重合体)という。これに対して,1種類のモノマーの構造単位のみから成るポリマーをホモポリマーhomopolymer(単独重合体)という。… ※「copolymer」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
